    Guozhi operating room

    After being called, she put on a surgical gown and stood beside the operating table. Xie Wanying helped the teacher observe the surgical field again, verified the three-dimensional picture emerging in her brain, and pointed out: "Teacher Du, there are several types of myocardial hypertrophy. This patient has deep central hypertrophy.  .¡±

    Myocardial hypertrophy, also called hypertrophic cardiomyopathy, is divided into three types. The main basis for classification is whether there is obstruction of the left ventricular outflow tract.  Those with no obstruction and occult obstruction do not rule out reversibility, and are not within the indications for surgery. Therefore, surgery does not necessarily require surgery for myocardial hypertrophy.  Among them, only the obstructive type requires surgery.

    Obstructive myocardial hypertrophy, that is, the left ventricular outflow tract is blocked.  Doctors used to call this type subaortic stenosis.  After doctors opened the hearts of such patients, they found that the abnormal hypertrophy of the myocardium was mainly under the aortic valve.

    Under the aortic valve is the aortic root, which is connected to the left ventricle and covers a relatively large area. If there is myocardial hypertrophy in this place, it is impossible to say that it is exactly the same.  The several types mentioned by Xie refer to the anatomical classification of the lesion structure here rather than the above classification.

    Doctors roughly classify myocardial hypertrophy into five types through surgery and dissection.  The simplest one is the hypertrophy of the muscle under the aortic valve that was discovered at the beginning. Other types of myocardial hypertrophy are deeper and more troublesome.

    Some hypertrophy is the hypertrophy of an entire interventricular septal muscle, with the hypertrophy extending across one side of the left ventricle.  Some aortic valves are not hypertrophic at all, but the hypertrophy reaches the apex of the heart, which completely subverts the initial definition and name of this disease by doctors, which is why the original name has become history.  Regardless of the location of the hypertrophy, the hypertrophy squeezes the normal left ventricular volume and creates obstacles to healthy left ventricular hemodynamics.  Doctors will definitely need to perform surgery.

    The point of dispute once again returned to the original place: Does the patient's myocardial hypertrophy in front of me conform to what Xie said is one of the pathological structures of obstructive myocardial hypertrophy?  Or is it that the preoperative examination report failed to clearly point out this kind of problem and judged it to be a reversible hidden obstruction, so the surgeon did not need to consider this aspect of the operation before the operation?

    Which result is correct?

    If it weren¡¯t for the mitral valve orifice problem, no one would have considered this at all.  Sometimes when there is a problem somewhere, I find the crux of the problem and move on to another problem.

    "Could you explain again, is the entire ventricular septum hypertrophic?" Du Yeqing continued to confirm what she said.

    "Is that so?" Dr. Yu, the assistant on the stage, tried to stand on tiptoes and stretch his neck, trying to see clearly the internal structure of the heart in the surgical field.

    When performing open heart valve surgery, the valve is located inside the heart, and the doctor will definitely need to cut open the heart to see and operate.  This must not be done randomly. It is impossible for the doctor to say that in order to make it easier for him to see clearly and operate easily, he opened the patient's heart completely with one knife.

    It is even more impossible to say that a knife can cut out the entire heart of a patient, because the heart is not an apple or a pear. It has several cavities, and these cavities and the walls that separate the cavities are all asymmetrical, left, right, up and down.  Asymmetrical, asymmetrical in volume, no symmetry at all.  (Remember the website address: www.hlnovel.com
